Nonrelativistic and Relativistic Contributions to Spin-Momentum Locking and Spin Photogalvanic Effect in an Altermagnetic Multiferroic
Giuseppe Cuono, Subhadeep Bandyopadhyay, Amar Fakhredine +6
Altermagnetic multiferroics provide a platform where non-relativistic spin-momentum locking (SML) coexists with relativistic spin textures, yet disentangling their different origin…
Anharmonic phonon coupling enabled by local inversion symmetry breaking at domain walls in ferroelastics
Seyyed Jabbar Mousavi, Vivek Unikandanunni, Niccolo Sellati +7
In ferroelastic materials, spontaneous symmetry breaking leads to the formation of twin domains. Although the bulk crystal typically remains centrosymmetric, inversion symmetry can…
Charge and spin photogalvanic effects in the p-wave magnet NiI2
Giuseppe Cuono, Srdjan Stavric, Javier Sivianes Castano +4
NiI2 is an exotic van der Waals material in which a noncollinear spin spiral breaks spatial inversion symmetry without sizeable structural distortion, generating improper ferroelec…
Magnetic anisotropy from interligand hopping in strongly correlated insulators: application to the magnon spectrum of CrI
Evgenii Barts, Paolo Barone, Maxim Mostovoy
Spin-orbit coupling (SOC) gives rise to complex magnetic states such as spin liquids, skyrmion crystals, and topological spin-wave excitations. We consider exchange interactions in…
Role of ionic quantum-anharmonic fluctuations on the bond length alternation and giant piezoelectricity of conjugated polymers
Stefano Paolo Villani, Lorenzo Monacelli, Paolo Barone +1
Functionalized conjugated polymers are promising materials for electromechanical applications due to predicted giant piezoelectricity, arising from anomalously large dynamical effe…
Unconventional Magnetism, Sliding Ferroelectricity, and Magneto-Optical Kerr Effect in Multiferroic Bilayers

Qian Song, Srdjan Stavrić, Paolo Barone +11
Magnetic states with zero magnetization but non-relativistic spin splitting are outstanding candidates for the next generation of spintronic devices. Their electron-volt (eV) scale…
Magnetoelectricity of Topological Solitons in 2D Magnets
Alexander Edström, Paolo Barone, Silvia Picozzi +1
We develop a multiscale approach to magnetoelectric effects, bridging atomistic and continuum models, with all parameters determined from ab initio electronic structure calculation…
Giant non-reciprocal band structure effect in a multiferroic material
Srdjan Stavrić, Giuseppe Cuono, Baishun Yang +5
Multiferroic materials, characterized by the coexistence of ferroelectricity and ferromagnetism, may unveil band structures suggestive of complex phenomena and new functionalities.…
Ternary nickel hydrides: a new platform for unconventional superconductivity and quantum magnetism
Mateusz Domanski, Antonio Santacesaria, Paolo Barone +2
In this letter, we propose ternary nickel hydrides MNiH2 (M = Li, Na) as new materials that mimic cuprate physics but have important differences and interesting properties. Ni-H ba…
Rearrangement of orbitals in KAgF3 due to Kugel-Khomskii mechanism: a Neutron diffraction and Density Functional Theory study
Kacper Koteras, Sebastian Biesenkamp, Paolo Barone +6
The crystal structure of KAgF3 was studied by powder neutron diffraction. KAgF3 exhibits at all temperatures an orthorhombic symmetry in space group Pnma that allows for several di…
Dilemma in All-optical Characterization of Single-layer NiI2 Multiferroics
Yucheng Jiang, Yangliu Wu, Jinlei Zhang +3
Matters Arising in Nature on "Evidence for a single layer van der Waals multiferroic". The search for two dimensional multiferroic materials is an exciting yet challenging endeavor…
Half-metallic ferromagnetism in layered CdOHCl induced by hole doping
